I'm looking for some advice on a Lefroy basin tap. I have a tap where I need to remake the seal where the spindle of the tap goes into the body, through the gland nut. There looks to have been an o-ring, which has perished and there is a weep now when the tap is open, so I want to remake the seal. Lefroy tell me the design of the tap has changed and they can't tell me the size of the o-ring. I am thinking I just need an o-ring which will fit over the spindle snuggly, use some silicone grease where the o-ring is going to sit and then tighten the gland nut carefully, with some PTFE tape on the thread of the gland nut.

I have done the same repair on garden taps just using just PTFE, but does my route using the right sized o-ring etc. described above sound right?

Hi Dave, thanks for the reply. My tap could be like that, but I'm not sure how to get the spindle out to see. I have removed the brass jumper that takes the main washer and have it as it is in the picture below. I'm guessing I should I push from the thread end at the base?
It's a Lefroy LB1422 basin tap.
